The popular Glock G43X and G48 now come in an optics-ready platform.

One of the hotter trends in the firearm industry remains carry optics. More carriers continue to turn to optics on their pistols, with new optic platforms smaller and more reliable than ever before. To capitalize on this trend, Glock announced the Slimline optics-ready G43X and G48 pistols now offer the Modular Optic System (MOS) configuration.

Glock Optics-Ready G43X, G48 Pistols

Both chambered in 9mm, the MOS pistols feature a micro-optic-ready, factory-milled slide and a slim rail. First released in July 2019, the Glock 43X and Glock 48 utilize the company’s Slimline frame. They also feature a 10-round magazine capacity. The MOS feature requires a specific, micro-reflex optic, like the Shield RMSc.

Both pistols features a super slim build. How slim? Well, 1.10 inches into total width and a slide width of just 0.87 inches. So, yeah, it’s pretty small. And from our tests, we can confirm they’re solid shooting guns.

The slim design allows the optical sight mounted closer to the shooter’s line of sight. It also eliminates the need for high, back-up sights, according to Glock. Shooters can see their standard sights through the optic. A non-standard accessory rail allows for light attachment. The system enables shooters to maintain a two-handed grip.

“Engineered with the GLOCK perfection promise, the two new models are the first Slimline pistols to offer an MOS option and are ideal for shooters everywhere,” said Shelby Lasater, GLOCK, Inc. Director of Marketing. “The versatility of the Slimline MOS models give them the adaptability and ease of use for concealed carry, target shooting, law enforcement, and competition which make them a new favorite.”

Lastly, both new models incorporate Gen5 technologies, which includes a nDLC finish for durability. A reversible magazine catch and match-grade Glock Marksman Barrel round out the features. As for MSRP, we don’t have that info yet, but expect it soon. For more information, please visit
